IMPROVEMENT IN OOOKING-STOVES AND RANGES i.

To ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES SPEAR, of the 'city and county ofPhiladelphia, and State of Pennsylvania, have invented a newand usefulImprovement in Cooking-Stoves and Ranges; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, in which Figure 1is a perspective'view of the stove.

Figures 2 and 3 are sectional'views of the front of the stove.

Figure 4 is a-perspective view of the back plate of-the stove,shovringthe raised or ornamental knobsbnthe back of the stove, as L L LL. V

Figure 5 is a sectional view of the stove inverted, resting upon theknobs L.

The nature of my invention consists in supplying the backplate of acooking-stove orrange' with raised or ornamental knobs, projectingbeyond the line of-the top and bottomplates'of the'stove, as showninfigs. 4 and 5, so that, in handling or shipping, the stove must restupon these knhbs, thus protecting'the edges of the top or bottom platefrom breaking.

In figs. 4, and 5, L L L L arcthe raised or ornamental knobs; the topplate of the stove; G, the bottom plate; 0, the back; and M is a linerepresenting the floor, showing how the raised or ornamental knobsprevent the flanges of the top and bottom plates from resting on thefloor. 1

And, also, in supplying a cooking-stove or range with double slidingdoors above thefire-grate, known as feed-doors. The under doors arecomposed of cast iron, with a few holes in them, to supply air to thefire while in the process of kindling. The outer doors are composed ofcast iron and perforated tin or brass, with a much greater quantity ofopenings in them, so that,when the fire is ignited, the under doors canbe withdrawn, andthe fire canbe supplied with a greater quantity of air,for the purpose of consuming all the gases arising from the fuel. At thesame time, the perforated tin acts as an illuminator. With thisimprovement, I accomplish two objects, that of consuming the gasesarising from the fuel, and also the cooling of the top of the stove whenone or both doors are thrown open.- g

It is a well-known fact to'all persons using cooking-stoves orrangcsthat, when-the fire is thoroughly ignited, there is considerabledifiiculty experienced in regulating the heat while baking.

With ordinary cook-stoves, when the feed-door is thrown open, it coolsoil the stove too rapidly, and in those stoves not supplied with afeed-door the covers have to be removed, which is very objectionable,particu- With my invention, I overcome these objections, as these doorscan be partiallyppened, and the heat regu-- lated-thereby.

To e'nableothers skilled in the arts to make and use my invention, takeany of the well-known cookingstoves, suel1'as the Ironsides, Farmer,Excelsior, Niagara, or any ordinary cooking-stove, and remove thefeed-door from the top plate, and, instead thereof, place a projectionon the front plate, above the fire-grate, with an opening or openings init, and cover-this opening with double sliding doors, as is shown infigs. 1, 2, and 3. v I I In figs. 1, 2, and 3, A A are the outerperforated doors B B, the under cast-lron doors; 1), the guide in whichcloorsslide; C, the front plate; H, the grate; 'F, the fireplace, and Ethe top plate. The air. entering the perforations in the door,is-denoted by black arrow-heads.

I am well aware that stoves have been supplied with feed-doors; also,double doors have been supplied to parlor-stoves, composed of perforatedtin and mica, and of perforated tin and cast iron; but these doorsconsist of but one door, and can only be used as such, as each partcannot be used separately.

I do not claim the inventions of G. R. Moore, August 13, 1867, and G. W.Walker, June 19, 1866.

'Noido I confine myself to any particular device for the purpose ofmoving these doors, as 'oneiset of doors may be hinged "to the stove,and the other may slide in grooves, or both may be hinged, workingindependently of each other. I

Having thus fully described my invention, I claim, and wish to secure byLetters Patent- 1. The application of double doors to a. cooking-stoveor range, above the fire-grate, constructe manner and for thepurposesubsatemtielly as herein described.

'2. The application of raised or ornamental knobs on the back plate of acooking-stove,

d in the for the purpose substantially as herein described. I
